Demi Lovato Leaves Hospital, Enters Rehab: Report

"Her family and team have decided that the best situation for Demi to focus on her sobriety is to check into an in-patient facility," a source toldEntertainment Tonight. "This approach was based on what has worked for Demi in the past, when she lived in an in-patient rehabilitation center over a year [in 2010]."

According to TMZ, Lovato took a private plane to the unnamed facility, reportedly outside of California, where she is expected to stay for "an extended period of time."

The news comes less than a day after Lovato spoke out about her recovery, writing in a statement posted to Instagram that she was thankful for everyone's support, and that she now needs "time to heal and focus on [her] sobriety and road to recovery."

“What I’ve learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet," she said.

According to ET's source, Lovato's family and friends were initially worried she would "go back to her old ways," but the reported overdose has apparently put things into perspective for the 25-year-old singer, who has publicly struggled with addiction throughout her career and was previously sober for six years.

"She is saying she is very scared of how quickly her life spiraled out of control and she is willing to do whatever it takes to get her life in order," the insider explained.

"She regrets letting it get this far because she has a tremendous amount of support," they continued. "She also realizes her first instinct as an addict was to pull away and isolate herself from her family and true friends. She feels confused and overwhelmed because she thought her life was going well until it all came crashing down so fast. She never realized how bad it had become."

Despite the relapse, though, Lovato pledged in her Instagram statement she would "keep fighting."
